8. UDC2RDREQ (UDC2 Read Request register)
Symbol
The bit for requesting read access to the UDC2 registers. Setting this bit to 1 will make a
read access to the address set in the udc2rdadr bit. When the read access is complete and
the read value is set to UDC2 Read Value register, this bit will be automatically cleared
and the UDINTSTS<int_udc2_reg_rd> bit of Interrupt Status register will be set to 1.
During a write access to UDC2 registers, it works as a status bit which indicates the
access being made to display the value of 1. Subsequent accesses to UDC2 registers
should not be made while this bit is set to 1.
0y0: No operation
0y1: Issue read request
The bit for forcibly clearing the read/write access request of UDC2 registers. Setting this
bit to 1 will forcibly stop the register read request/UDC2 write access by udc2rdreq and
the value of udc2rdreq will be 0. After the forced clearing completes, this bit will be
automatically cleared to 0. When interrupted, the read and write values during the access
will not be secured.
0y0: No operation
0y1: Issue forced clearing
<udc2rdadr>
Sets the address of the UDC2 register (upper 8 bits) to be read. It should be set in
combination with the udc2rdreq bit mentioned above.
will be saved in the UDC2 Read Value register.
